Detailed Description of the Preferred Embodiments

[0029] The following further describes the specific embodiments of the present utility model with reference to the accompanying drawings.

[0030] As Figures 1 - 5 shown, a deep foundation pit steel waling device of the present utility model includes a rotating assembly 1, a telescopic assembly 2 and a connecting member 3. There are two telescopic assemblies 2 and two connecting members 3, which are arranged at intervals left and right. By designing a deep foundation pit steel waling device, the steel waling can meet the installation at different corners, improve the practicability, improve the work efficiency, and at the same time achieve the purpose of rapid disassembly of the steel waling, reducing the cost.

[0031] During the use process, in order to facilitate the connection between the connecting member 3 and the telescopic assembly 2, in this embodiment, each telescopic assembly 2 includes a rotating block 201, a sliding block 202 and a mounting plate 203. On the opposite sides of the two rotating blocks 201, sliding grooves 8 with opposite opening directions are provided.

[0032] The rotating block 201 includes a rectangular block and an elliptical block. In this embodiment, the rectangular block and the sliding groove 8 are arranged such that the sliding block 202 can be limited. The rectangular block and the elliptical block are fixedly connected to each other, and the elliptical blocks on the two rotating blocks 201 are stacked against each other. The sliding groove 8 is formed in the rectangular block.

[0033] The sliding block 202 is slidably inserted into the sliding groove 8. A limiting hole is formed in the rotating block 201, and the limiting hole communicates with the sliding groove 8. The sliding block 202 is inserted into the sliding groove 8, and the first locking assembly 4 is threaded through the limiting hole and connected to the sliding block 202. The first locking assembly 4 is arranged on the sliding block 202 through the limiting hole.

[0034] The first locking assembly 4 includes a second locking bolt 401 and a second rotating disk 402. The second rotating disk 402 facilitates rotation. The second rotating disk 402 is fixedly arranged on the second locking bolt 401. A second threaded groove is formed in the sliding block 202. The second locking bolt 401 passes through the limiting hole and is threadedly connected to the second threaded groove. In this embodiment, when the second locking bolt 401 is tightened, the second rotating disk 402 will be pressed against the rotating block 201, so that the sliding block 202 cannot slide along the sliding groove 8. If the second locking bolt 401 is loosened, the sliding block 202 can slide along the sliding groove 8, and the second locking bolt 401 will also move along the limiting hole to adjust the moving distance.

[0035] The mounting plate 203 is fixedly arranged on the side of the sliding block 202 away from the rotating block 201, and a plurality of bolt holes are formed in the mounting plate 203.

[0036] The connecting member 3 is provided with mounting holes corresponding to the bolt holes one by one. Bolts 10 are arranged in the mounting holes. The bolts 10 pass through the bolt holes and the mounting holes and are threadedly connected to nuts 11 to connect the connecting member 3 and the mounting plate 203 to each other. In this embodiment, since the bolt holes and the mounting holes correspond to each other, when connecting, after the bolts 10 pass through the bolt holes and the mounting holes, the nuts 11 are threadedly sleeved on the bolts 10, and the connecting member 3 and the mounting plate 203 can be connected to each other and adjusted along with the sliding block 202.

[0037] In order to facilitate the adjustment of the angle between the two connecting parts 3, in this embodiment, a plug-in component 5 that can move up and down is provided in the rotating component 1, and the two telescopic components 2 are respectively provided with through holes 6 for the plug-in component 5 to be plugged in. The plug-in component 5 is provided with a detachable second locking component 7, and the second locking component 7 can lock the plug-in component 5. In this embodiment, the second locking component 7 adopts a third locking bolt. When rotation is not required, the second locking component 7 is inserted into the connecting shaft 103 and tightened, so that the top plate 101 and the lifting plate 503 can be squeezed on the two rotating blocks 201 to prevent the two rotating blocks 201 from rotating.

[0038] Specifically, the rotating assembly 1 includes a top plate 101 , a bottom plate 102 and a vertically arranged connecting shaft 103 . The bottom plate 102 is fixed to the bottom of the connecting shaft 103 , and the connecting shaft 103 is slidably inserted into the top plate 101 .

[0039] In this embodiment, during installation, one of the rotating blocks 201 is first put on the connecting shaft 103, and then the other rotating block 201 is put on the connecting shaft 103. At this time, the two rotating blocks 201 are stacked together, and then the insert sleeve 501 is put on the connecting shaft 103. Since the connecting shaft 103 is adapted to the size of the through hole 6, after the sleeve 501 is put on, the two rotating blocks 201 can be on the same center of a circle, avoiding misalignment of the rotating blocks 201. Then the top plate 101 is put on the connecting shaft 103, and finally the lifting plate 503 is fixedly connected to the sleeve 501. In this embodiment, the connection method between the lifting plate 503 and the sleeve 501 is threaded connection.

[0040] The plug-in assembly 5 is slidably mounted on the connecting shaft 103 .

[0041] The plug-in assembly 5 includes a vertically arranged sleeve 501, a plug-in plate 502 fixed on the sleeve 501, and a lifting plate 503. The plug-in plate 502 is divided into two groups spaced apart in an upper and lower manner. When the sleeve 501 and the lifting plate 503 are lifted upward, the plug-in plate 502 will be lifted together, so that the plug-in plate 502 will be separated from the plug-in hole 9. At this time, the two rotating blocks 201 can be rotated to adjust the angle of the rotating block 201.

[0042] The lifting plate 503 is arranged at the upper end of the sleeve 501. The sleeve 501 and the lifting plate 503 are both slidably mounted on the connecting shaft 103. A through hole is opened on the top of the lifting plate 503. The second locking component 7 can pass through the through hole and be threadedly connected to the connecting shaft 103. After the plug-in plate 502 is inserted into the plug-in hole 9, the second locking component 7 can be threadedly connected to the connecting shaft 103 to squeeze the lifting plate 503 and the top plate 101 downward, so that the rotating block 201 is locked and cannot rotate.

[0043] A plug hole 9 is provided in the through hole 6, and the plug plate 502 is plugged into the plug hole 9 to limit the rotation of the rotation block 201. When the sleeve 501 is sleeved on the connecting shaft 103, both sets of plug plates 502 are inserted into the plug hole 9 to limit the rotation of the rotation block 201.

[0044] Working principle: The bolt hole and the mounting hole correspond to each other, so when connecting, after passing the bolt 10 through the bolt hole and the mounting hole, the nut 11 is threaded onto the bolt 10, so that the connecting member 3 and the mounting plate 203 can be connected to each other. When the second locking bolt 401 is tightened, the second rotating disk 402 will be squeezed on the rotating block 201, so that the sliding block 202 cannot slide along the sliding groove 8. If the second locking bolt 401 is loosened, the sliding block 202 can slide along the sliding groove 8, and the second locking bolt 401 will also move along the limit hole to adjust the moving distance.

[0045] When the sleeve 501 and the lifting plate 503 are lifted upward, the plug-in plate 502 will be lifted together, so that the plug-in plate 502 will be out of the plug-in hole 9. At this time, the two rotating blocks 201 can be rotated to adjust the angle of the rotating block 201. After the plug-in plate 502 is inserted into the plug-in hole 9, the second locking component 7 can be threaded and connected with the connecting shaft 103 to press the lifting plate 503 and the top plate 101 downward, so that the rotating block 201 is locked and cannot rotate.

[0046] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is determined by the appended claims rather than the foregoing description. It is intended that all variations within the meaning and range of equivalents of the claims be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
